Moly Grease

[tarbe]

So when you rebuild the front axles you should use moly grease for the birfields and lithium grease for the wheel & trunion bearings?

UPS tracking said I should get my parts today, so I'm probably going to attack that this weekend. Want to make sure I have the right stuff.

Trunion bearings are low-speed (obviously) so moly is actually ok in there...even though Mr. T says to use non-moly. The lower bearing is going to end up with some moly in it from the knuckly/birf anyway!

If you have Jim's DVD, that's my 80 getting done! Hope your job goes well.

My understanding is that adding moly through the check hole has little to no chance of actually lubricating the birf.

This was the prominent theory presented by some for a while, but was disproved last year (by Idahodoug IIRC). Grease added through the fill whole thoroughly and completely circulates and mixes with the existing grease AND into the birf joint.
